dc.description.abstractIn this research we report deposition of thin films from the already synthesized chalcohalide (GeS1.5)1-x(AgI)x glasses, where x=5, 10, 20 mol.%. The bulk samples used and the corresponding layers are checked by XRD analysis which reveals only a diluted halo on the respective diffractograms. Some basic optical parameters of the investigated Ge-SAgI thin films are estimated and their relation with materials' composition is determined. The influence of the third component on the optical absorption is discussed. The optical energy gap (Eg) is determined from the Tauc plot h =B(EgTauc - h )2 and Eg 04 is found from the relationship a=f(hv ). The Eg values calculated by both methods reveal slight increase with silver iodide addition probably due to structural changes.© 2013 The Authors. Published by Elsevier B.V.
